Product Description

Brazed Plate Heat Exchangers

Brazed plate heat exchanger is a kind of heat transfer equipment with highly compact structure and high heat transfer efficiency. It consists of a series of thin stainless steel metal plates with special corrugated shapes stacked on top of each other, and the corrugations of the adjacent plates cooperate with each other to form complex flow channels. The most critical feature is that it does not use the traditional rubber sealing gasket between the plates, but in the vacuum brazing furnace, the use of high temperature will be copper (or nickel) brazing material melting penetration into the plate contact point, to achieve the permanent, high strength metallurgical bonding of the plate stack.

Highly efficient heat transfer

Compact

Pressure and temperature resistance

Unique corrugated sheet design induces strong turbulence, the heat transfer coefficient is much higher than the traditional heat exchanger (such as shell and tube), significantly improving efficiency.

Huge heat exchange area per unit volume, the volume and weight is only a fraction of the traditional heat exchanger of the same capacity, greatly saving space.

Fully brazed metal sealing structure (no rubber gaskets) enables it to withstand higher working pressures and working temperatures with greater reliability.

Maintenance-free design

Operating economy

Wide range of applications/reliable materials

The gasketless design completely eliminates gasket deterioration, corrosion, leakage and the maintenance needs and costs of regular gasket replacement.

Ultra-high heat transfer efficiency means that under the same working conditions, the required heat transfer area is smaller, the initial investment in equipment is reduced, and at the same time, the fluid resistance loss is relatively low (especially with high turbulence matching), the pumping energy consumption is more economical.

Mainly using stainless steel sheet and copper (or nickel) brazing material, with good corrosion resistance and compatibility, widely used in refrigeration, air-conditioning heat pumps, industrial processes, hydraulic systems, waste heat recovery and many other fields.

Advantages of brazed plate heat exchanger plates

As the core element of the heat exchanger, brazed plate, through the precision stamping herringbone corrugated design (inducing strong turbulence of fluid to significantly improve heat transfer efficiency) and vacuum brazing metallurgical sealing technology (copper/nickel instead of rubber gaskets to achieve a permanent metal bonding), in ultra-thin stainless steel (0.4 ~ 0.8mm) on the simultaneous solution to the problem of high-efficiency heat transfer and structural sealing, and ultimately endowed with the heat exchanger's ultimate compactness, Excellent pressure and temperature resistance (copper brazing ≤ 30bar/250 ℃, nickel brazing ≤ 80bar/400 ℃) and the core advantage of lifelong maintenance-free, become the ideal choice for refrigeration, heat pumps and industrial high-pressure heat transfer field.

Cleaning and maintenance

Professional Intervention

In the brazed plate heat exchanger maintenance, to regularly check the temperature, pressure, flow and other parameters, once found abnormalities need to be dealt with in a timely manner; at the same time need to ensure that the water quality is qualified, through the addition of filters and regular cleaning, in order to prevent the emergence of scaling and clogging problems.

For minor fouling of the heat exchanger, low concentration of acid or alkali can be used for on-line cycle cleaning, the process needs to strictly control the time and temperature to prevent corrosion; at the same time, it is strictly prohibited to use mechanical violence to clean up, to avoid damage to the brazing structure.

In the brazed plate heat exchanger maintenance, to avoid vibration, freeze cracks and abnormal flow rate, long term out of service need to drain the internal fluid and keep it dry; if leakage or serious clogging occurs, it is not recommended to dismantle it by yourself, and it should be detected or replaced by professional personnel.
